Petrobras strikes new ultra deepwater discovery
The well is 85 km off the Aracaju coast, state of Sergipe, at a water depth of 2,583 metres

Petrobras on Wednesday announced the discovery of a new light hydrocarbon accumulation in ultra deep waters of the Sergipe-Alagoas Basin, in block SEAL-M-424.

Petrobras’s fourth major deepwater discovery in the basin this year, the discovery took place during the drilling of well 1-BRSA-1108-SES (1-SES-172).

The well is 85 km off the Aracaju coast, state of Sergipe, at a water depth of 2,583 metres. Drilling was completed at a depth of 5,347 metres.

Known as Muriú, the well was discovered in the reservoirs of the Calumbi formation. The discovery was confirmed through log data analysis. Pressure data analysis and fluid sampling from the reservoirs indicated the presence of light oil. Petrobras is the only operator of the SEAL-M-424 concession.

Petrobras will proceed with logging operations (records of features of a formation) and to gather rock and fluid data from this well, with the aim of preparing the assessment strategy of the new discovery, as well as to characterize the conditions of the reservoirs found. The next step will be to submit the Discovery Assessment Plan to the National Petroleum Agency (ANP).
